Since it's a graphic novel about the Tetris story, the main character is likely to be Alexey Pajitnov, the creator of Tetris.

There could be a young gamer who is really good at Tetris. And perhaps another gamer, male or female, who is initially a rival but then becomes a love interest.

Atreyu is one of the main characters. He is a young warrior from the Plains People. Then there is Bastian, a boy from the real world who gets drawn into the story. And of course, Falkor, the luck dragon, is also a very important character. He helps Atreyu on his journey.

There could be a variety of main characters. It might be an intrepid explorer who is on a mission in the polar regions. Or perhaps a group of Inuit people who have their own stories and traditions in the polar area.

It could be that the main characters are the arsonist, if it's a story about an intentionally - set fire, and the detective or investigator trying to catch them. Or it could be a group of neighbors who come together during the fire to support one another. Each character would bring their own perspective to the story.

The main characters are of course the members of The Beatles: John Lennon, Paul McCartney, George Harrison, and Ringo Starr.
